Sucrase-isomaltase deficiency can be diagnosed via disaccharidase enzyme testing from duodenal mucosal biopsies. Dietary restriction and sacrosidase supplementation are effective, based on randomized controlled trials, in children with genetic sucrase-isomaltase deficiency; however, they remain to be rigorously studied in adults.
